A Correct answer
Explanation

Speed = 66 kmph = 66 * (5/18) m/s = 55/3 m/s. Length of train = Speed * Time = (55/3) * 18 = 55 * 6 = 330 m.

AI explanation

Use the formula distance equals speed multiplied by time, where the distance is the length of the train. First, convert the speed of 66 kmph to metres per second by multiplying by 5/18, which results in 55/3 m/s. Multiply this speed by the given time of 18 seconds to find the length. The length of the train is 55/3 times 18, which equals 330 m.
